The compounds having general formula (I) can be obtained with different processes.

When Z represents a group having general formula (V), the compounds having general formula (Ia) are obtained by a process which can be schematized as follows: ##STR14## wherein R₁, R₂, R₃, R_(c), R_(a), K₁, Ar, Q and W have the same meaning specified above.

The condensation reaction (i) schematized above, is carried out by reacting the derivative of the β-aminopropionic acid having general formula (IX) with the chloride having general formula (XI), in the presence of an organic solvent and an organic or inorganic base, at a temperature of between -10° C. and the reflux temperature of the solvent used.

Organic solvents which can be used for the purpose are: chlorinated organic solvents such as, for example, dichloromethane, 1,2-dichloroethane; aromatic solvents such as benzene, toluene; ether-type solvents such as diethyl ether, tetrahydrofuran; ester solvents such as ethyl acetate, propyl acetate; mixtures of the above solvents.

Organic bases which can be used for the purpose are, for example, triethylamine, N,N-dimethylaniline.

Inorganic bases which can be used for the purpose are, for example, sodium bicarbonate, potassium bicarbonate.

The chloride having general formula (XI) is, usually, a commercial product or can be easily obtained from the corresponding acid form having general formula (XII): ##STR15## wherein R_(a), K₁ and W have the same meaning described above, by reaction with a halogenating agent such as, for example, thionyl chloride, phosphorous pentachloride; or, when K₁ is oxygen, by treatment of the hydroxylic derivative having general formula (XIII):

    Ra--OH                                                     (XIII)

with phosgene, operating according to the processes known in literature.

When the compounds having general formula (Ia) have an R_(a) -K₁ group which cannot be obtained by the process described above (i), it is possible to use, instead of the chloride having general formula (XI), the mixed anhydride of the acid having general formula (XII) or the acid itself having general formula (XII). In this case, the condensation reaction (i) is carried out in the presence of a condensation reagent such as, for example, cyclohexylcarbodiimide, carbonyldiimidazol, operating under the same conditions described, for example, in "The Practice of Peptide Synthesis" (1984), pages 7-150, Springer-Verlag Ed.; or, it is also possible to use other methods described in literature relating to the functionalization to nitrogen of aminoacidic or peptidic derivatives such as, for example, those described in "The Practice of Peptide Synthesis" (1984), pages 7-150, Springer-Verlag Ed.

When Q represents a group having general formula (III) and R₁, R₂ and R₃ are hydrogen, the derivative of β-aminopropionic acid having general formula (IX) can be obtained, for example, according to the method described in "Tetrahedron Letters" (1988), Vol. 29, page 6465.

When Q represents a group having general formula (III) and R₁, R₂ and R₃ are hydrogen, or at least one of the substituents among R₁, R₂ and R₃ is different from hydrogen and represents a C₁ -C₈ alkyl or haloalkyl group, linear or branched, the derivative of β-aminopropionic acid having general formula (IX), can be obtained by the opening of the corresponding β-lactam having general formula (XIV): ##STR16## wherein R₁, R₂, R₃ and Rc and Ar have the same meaning described above, with the compound having general formula (XV):

    H--Y--K.sub.2 --R.sub.b                                    (XV)

wherein Y, K₂ and R_(b) have the same meaning described above, possibly in the presence of an organic base such as, for example, sodium hydride, potassium carbonate; or a mineral acid such as, for example, sulphuric acid, hydrochloric acid; or a Lewis acid such as, for example, zinc chloride, boron trifluoride etherate; or chlorotrimethylsilane; and in the presence or absence of a chlorinated organic solvent such as, for example, dichloromethane, 1,2-dichloroethane; or an aromatic solvent such as, for example, benzene, toluene; or a dipolar aprotic solvent such as, for example, N,N-dimethylacetamide. The above reaction is carried out at a temperature of between -10° C. and 120° C.

The β-lactam having general formula (XIV) can be obtained by the cycloaddition of a suitable olefin and N-chlorosulphonylisocyanate operating according to the method described, for example, in "organic Preparations and Procedures International" (1973), Vol. 5(1), page 13; "Tetrahedron Letters" (1987), Vol. 28, page 227; "Tetrahedron Letters" (1970), Vol.3, page 245; "Tetrahedron Letters" (1977), Vol. 41, page 3643; "Journal of Organic Chemistry" (1984), Vol. 41, page 1397.

The β-lactamic compound having general formula (IXa), when R_(L) has the same meaning as the group having general formula (IXb), can be prepared from the β-lactam having general formula (XIV), when R_(c) is hydrogen, by condensation with the chloride (XI), under the conditions described in "Tetrahedron Letters", Vol. 31, page 6429 (1990).

Also when Q represents a group having general formula (III) and R₂ is a C₁ -C₂ alkylenic chain which is linked to a carbon atom forming the Ar group, the derivative of β-aminopropionic acid having general formula (IX) can be obtained, for example, by the opening of the corresponding β-lactam having general formula (XIV), operating under the same conditions described above, in turn prepared by the cycloaddition of an indene suitably substituted in the aromatic portion and N-chlorosulphonylisocyanate as described, for example, in "Organic Preparations and Procedures International" (1973), Vol. 5(1), page 13.

When Q represents a group having general formula (III), R₂ together with R_(b) represents a direct bond and K₂ is not a direct bond, the derivative of β-aminoproprionic acid having general formula (IX), can be obtained by the addition of a suitable benzylamine having general formula (XVI): ##STR17## wherein R₁₄ represents a C₁ -C₈ alkyl or haloalkyl group, linear or branched, to a β-ketoester having general formula (XVII): ##STR18## wherein R₁, K₂, Ar and Y have the same meaning described above, operating under the same conditions described, for example, in "Tetrahedron" (1993), Vol. 49, page 1579.

From the above addition reaction, an imine derivative is obtained having general formula (XVIII): ##STR19## which is subsequently reduced, for example, by reaction with a borane operating according to the method described, for example, in "Tetrahedron Asimmetry" (1994), Vol. 5, page 1455, to obtain the derivative of β-aminopropionic acid having general formula (IX) wherein R_(c) is benzyl and R₃ is hydrogen.

When R₁ is different from hydrogen, the imine derivative having general formula (XVIII), can be added to a lithium derivative having general formula (XIX):

    R.sub.3 --Li                                               (XIX)

wherein R₃ has the same meaning described above, in the presence of an ether-type solvent such as, for example, tetrahydrofuran, at a temperature of between -78° C. and -20° C., obtaining the derivative of β-aminopropionic acid having general formula (IX) wherein R_(c) is benzyl and R₃ is different from hydrogen.

Operating with the same procedures described above for β-ketoester having general formula (XVII), it is possible to easily prepare many of the compounds having general formula (I), by the addition of a suitable benzylamine having general formula (XVI) to an appropriate β-ketone having general formula (XX): ##STR20##

In both of the cases described above, if the benzyl group of the amine having general formula (XVI) is optically active, the product obtained will also be optically active as described in the literature specified above. This benzyl group can be easily removed by hydrogenation in the presence of palladium oxide (Pd(OH)₂ as catalyst, operating according to the method described, for example, in "Tetrahedron Asimmetry" (1991), Vol. 2, page 183.

A further procedure for obtaining the derivative of β-aminopropionic acid having general formula (IX) in one of the particular cases mentioned above, and in particular in the case wherein R₅ is different from hydrogen, consists in the addition of an anion having general formula (XXI): ##STR21## wherein R₁, R₂, Y, K₂ and R_(b) have the same meaning described above or of one of its equivalent synthon, to an iminic derivative having general formula (XXII): ##STR22## wherein R₃ and Ar have the same meaning described above and R₁₅ has the same meaning described above for the substituent R_(c), or represents a benzylic group, to obtain a compound having general formula (XXIII): ##STR23##

The reaction described above can be carried out operating according to numerous methods described in the art such as, for example, in "Angewandte Chemie" (1989), International Edition, Vol. 28, page 1068; "Tetrahedron Letters" (1991), Vol. 32, page 3151; "Chemical Pharmaceutical Bulletin "(1978), Vol. 26, page 260. This reaction is particularly useful when compounds are to be obtained having general formula (IX) wherein R₁ is trifluoromethyl, R₂ is hydrogen or a C₁ -C₈ alkyl or haloalkyl group; or compounds having general formula (IX) wherein R₁ and R₂ are fluorine. These compounds can be obtained in fact using as equivalent synthon to the anion having general formula (XXI), organic zinc described in "Chemistry Letters" (1987), page 1971 or organic zinc described in "Tetrahedron Letters" (1984), Vol. 25, page 2301, respectively.

(IX) wherein R_(c) is different from hydrogen, can be obtained from any compound having general formula (IX) wherein R_(c) is hydrogen obtained, in turn, with any of the methods described above, protecting the nitrogen atom with the tert.-butylbenzyloxycarbonyl group by reaction with a base such as, for example, potassium tert.-butylate, and with a halide having general formula (XXVII):

    R.sub.5 -Alog.                                             (XXVII)

wherein R₅ has the same meaning described above and Alog. is a halogen atom selected from iodine or bromine, operating under the same conditions described in "Journal of Organic Chemistry" (1989), Vol. 54, page 617.

When Q represents a cyano group, the derivative of β-aminopropionic acid having general formula (IX) can be obtained, for example, with the method described in "Tetrahedron Letters" (1990), Vol. 31, page 6379; or it can be obtained from the corresponding compounds having general formula (IX) wherein Q represents the group having general formula (III), by simply transforming the same group into amide and dehydrating this, operating with one of the many methods described in literature.

When Q represents a thiazolic group, the derivative of β-aminopropionic acid having general formula (IX) can be obtained from the corresponding compounds having general formula (IX) wherein Q represents the group having general formula (III), by simply transforming the same group into amide and dehydrating this operating, for example, as described in "Synthetic Communications" (1990), Vol. 20, page 2235, or in "Tetrahedron Letters" (1990), Vol. 46, page 8267.

Similarly, if in the desired derivative of β-aminopropionic acid having general formula (IX), Q represents a group having general formula (III) wherein the group Y--K₂ --R_(b) is not compatible with the preparative method selected, it is easy to prepare the derivative having general formula (IX) wherein the group Y--K₂ --R_(b) represents --O--CH₂ --Ph (Ph=phenyl) or --O--C(CH₃)₃ which, at the end of the reaction, can be easily removed, by, respectively, hydrogenation and by treatment with acids so as to obtain the corresponding acid of the derivative having general formula (IX) wherein Y--K₂ --R_(b) represents OH. This acid can then be easily transformed into the desired group having general formula (III) using one of the numerous methods described in literature such as, for example, in "The Practice of Peptide Synthesis" (1984), pages 89-150, Springer-Verlag Ed., after possible protection of the aminic group with, for example, groups which can be easily removed such as tert.-butoxycarbonyl and benzyloxycarbonyl, operating with the methods described, for example, in "The Practice of Peptide Synthesis" (1984), pages 89-150, Springer-Verlag Ed.

Compositions can be used which are in the form of dry powders, wettable powders, emulsionable concentrates, micro-emulsions, pastes, granules, solutions, suspensions, etc: the selection of the type of composition depends on the specific use.

The compositions are prepared in the known way, for example by diluting or dissolving the active substance with a solvent and/or solid diluent, possibly in the presence of surface-active agents.

Solid diluents or supports which can be used are: silica, kaolin, bentonite, talc, infusorial earth, dolomite, calcium carbonate, magnesia, chalk, clays, synthetic silicates, attapulgite, sepiolite.

As liquid diluents, apart from water of course, various solvents can be used, for example aromatics (xylols or mixtures of alkylbenzols), chloroaromatics (chlorobenzol), paraffins (petroleum fractions), alcohols (methanol, propanol, butanol, octanol, glycerine), amines, amides (N,N-dimethylformamide, N-methylpyrrolidone), ketones (cyclohexanone, acetone, acetophenone, isophorone, ethylamylketone), esters (isobutyl acetate).

Surface-active agents which can be used are salts of sodium, calcium, triethanolamine or triethylamine of alkylsulphonates, alkylarylsulphonates, polyethoxylated alkylphenols, fatty alcohols condensed with ethylene oxide, polyoxyethylated fatty acids, esters of polyoxyethylated sorbitol, lignin sulphonates.

The compositions can also contain special additives for particular purposes such as, for example, adhesion agents, such as arabic rubber, polyvinyl alcohol, polyvinylpyrrolidone.

If desired, it is also possible to add other compatible substances to the compositions of the present invention such as, for example, fungicides, phytoregulators, antibiotics, weed-killers, insecticides, fertilizers.
